Pruning fails to remove platform specific optional packages

• I have read the contribution documentation for this project.
• I agree to follow the code of conduct that this project follows, as appropriate.
• I have searched the issue tracker for an issue that matches the one I want to file, without success.

Starting from v12.0.0 I am getting

Failed to locate module "7zip-bin-linux" from "C:\p\rh\dpi\transpiled\node_modules\7zip-bin"

        This normally means that either you have deleted this package already somehow (check your ignore settings if using electron-packager).  Or your module installation failed.

when running on windows.

It seems the problem is in traversing development dependencies when --prune option is used. –no-prune fixes the issue, but only for development builds.

v11.2.0 works fine for both options.

Console output when you run electron-packager with the environment variable DEBUG=electron-packager,flora-colossus.

This should be fixed with https://github.com/MarshallOfSound/flora-colossus/pull/3

Also, this does not seem to be related to this particular bug (it’s related to optional dependencies), when you do create a minimal testcase, can you please file a new bug and follow the issue template?
